Be it known lthat I, EUGENE EARL NOR- f TON, a citizen ot the United Sta-tes,- and a resident ot' Bridgeport, inthe. countyof 'Fairfield and State of Connecticut, have invented certain new and'nsefnl- Improve- Vments in Speed-Controllers, of' which theA `i'follolwing is a specification. u

u This invention relates 'toaspeed controller, which is specially applicable to Inovlng pictureniachines, so that the fil1n'sproclr-- .et drums and other aiipurtenances thereof will be operated at a uniform speed, irrespective oi2 the variations in ,thefspeed oi the driving shaft of the speed controller.

Dion 52 is journaled on the end 49, and the teeth of said pinion "mesh with the teeth ot' the spur geare. 0n the square portion t8 or" the goif'ernor shaft are slidablvsup ported the grooved sleeve 5i with the groove atene end, and thedisk sleeve 56 at the other end. The latter has fastened to its outer'face the disl'S'of' leather Aor the like material, which hears'against the opposing face ai? the ily-Wheel 51, and the outer face of 4 the gr-ooved .sleeve 54 lbears against the opposingface ofthe collar The sleeves' 54. and are connected by the flexible bands 57 ywhich carry the Weights 60, and the collar l53 is located so that the flexible bands 57 arev always maintained in tension to always secure eontactv between the face ofi the liv-Wheel 5l and the disk 58, so thatrotation canl always be transmitted between the tivo latter elements. 4

A pair ofhevel 'disks 78 arejfastenedfto the rod 75 andstraddle the swinging end lofthe adjusting lever 6R The `facesofthe opening 6 9 in vthe leif'e'r are beveled'togag'e with the beveled portions onf-the diSks'YS. [The threads 7'? of the rod 75, engagea thr'eadedopening in the side plate and 'tl'iefother end o'said rod is 'supported in the bracket '749 secured to the base plateil A 'disk -Sn'itli a detent or: fnotcli; S5 is fastenedito the redfie, and a Sia-ingaat @with a. Wise-i0 .881e @as i from the base'plate 19,` 'the projection 88 being in the path of the notch 8G.

. On the cylindrical end 50 of the governor shaft is fastened .the pinion 9 0,- theteeth of which mesh ivith the teeth o f the spur` gear -91 ournaled on a pin 92,` extending from the sideplate The teeth ofthe spur gear 91 mesh with theteeth o f the spur gear 93 carried on the shaft 94, one end of which lat-4 ]0 'ter is'journaled in .the side plate-24 and theothcr .end of which is journaledin the pic ture machine. O n the-shaft 94 'is also fastened a spur gear, not shown, but, laxiallyin line ivith the spur gear 93 andthe teeth of which mesh with the teeth of the spur gear.

2.0 of a pinion 99 carried on the shaftlOO. The teeth of pinion 99 mesh with the teeth of the pinion 101 fastenedon the shaft 102fof the sprocket drum 103. The teeth ofthe gear 9 3 mesh .i'vith the teeth ofthe spur -gear104 on the shaft 1 05, on which is carried'the lower sprocket drum 106,

To luse the invention l.an operator turns the j driving shaft 25 by means of the crank 2G,

instead of attaching'a crank yto the shaft 98,

as would be the case without the present iinproveniente.

The rotations of the shaft 25 are transmitted to the fly Wheel-51 of the governor through'the' train of gears 2 9, 37 3G,- 40. 41,- 43 and 52. The disktl of the disk sleeve 56 bears against the face of the fly Wheel 51 by reason of the tension of the f flexible bands `The rotations of the said fly Wheel cause-the-shaf't of thegovernor to turn ivith a speed equal to the speed of said -40 fly wheel or a less number of turns, depending upon the pressure between the disk 58 of the disk sleeve 56, and the opposing face of said flywvheel 51. The rotations of the governor shaft are` transmitted to the train of gears 90, 91, 93 an'd then to the train of gearin in the' picture machine eoacting therewith to the shaft 9 8 and other shafts of said machine. If the operator turns the crank26'a't too great a speed the Weights 60 5er by centrifugal force will swing out and de.

crease the pressure betiveen the face of the fly Wheel 51 and the disk'S, by virtue of which the rotations of the governorshaft and consequently all the appurtenances of 55 the apparatus rotated thereby, Will be decreased in speed until the normal predeten. mined rate of speed is obtained. i

Bvmeans of the adjusting rod 75 an operator by turning the head 76 disengages the spllng latch 87 from the notch S6 and the adjustingvlever 67 is .swung in one direction or the other by reason of one of the .bevel disks 7 8 bearing against-the opposing faceof the lever 67. lThis Will cause' the grooved sleeve 54 to slide on the square portion 48 of thegovernor shaft, and either re-A lax or increase the pressure betvveen the face of the disk 5S andthe fly Wheel 51, detracting from or assisting the efl'ect of the cen' trifugal force of the weights 60 of the rllhere. is thus secured means and Vadjust said' governor,

governor. to (control so that it will 'govern at different speeds.

By this' means vvith the same speed of the driving shaft 25,' various uniform speeds F may beimpartedto they appurtenances of the picture machine, and the Hlm 1'( can be `moved at the most-desirable speed through the machine and which speed can be varied.

The stop pin 72' prevents the adjusting lever 67 from being swung too far, so as to obviat'e excessive pressure between the outer face of the grooved sleeve 54 and the collar 53', and which excessive pressure would prevent the rotation of the governor shaft and its appurtenances. The abutting journal sleeve 45 takes the end thrust of the hub of the pinion 52.
